Locking and unlocking with the detachable key blade

Amongst other things, the detachable key blade can be used to unlock the car from the outside - e.g. if the remote control key's battery has become discharged.

When the door is unlocked using the key blade and is then opened, the alarm is triggered.

It is also possible to lock the car with the remote control key's detachable key blade e.g. in the event of a loss of power or if the key's battery has become discharged.

The left-hand front door can be locked with its lock cylinder and the detachable key blade.

Other doors have no lock cylinders and instead have a lock switch on the end of each door which must be depressed using the key blade - they are then mechanically locked/blocked to prevent them being opened from outside.

The doors can still be opened from the inside.

  • A door's lock reset only locks that particular door - not all doors simultaneously.
  • A manually locked rear door with activated manual or electric child safety locks cannot be opened from either the outside or the inside. A rear door that is locked in this way can only be unlocked with the remote control key or central locking button.
  1. 1 This applies whether the car is right-hand drive or left-hand drive.
